3M Filtrete Filters
Authorized Retailer of 3M Filtrete filters including the Elite, Ultimate, Advanced, Ultra and Micro models. Filters can be hard to find for many people as brick and mortar stores only stock on average 5-10 sizes of 3M Filtrete filters, while 3M makes 31 sizes in both the Ultra and Micro models. We stock all models and sizes, giving you the perfect filter for your needs.
All Filtrete Air Cleaning Filters are electrostatically* charged. As air passes through the filter, airborne particles are attracted to and captured by the filters pleated fabric. 3M Filtrete electrostatic filters capture both large and small particles** down to 0.3 microns in size. This is different from fiberglass, washable, and non-electrostatic pleated filters, which have no charge. Without electrostatic properties, these other filters cant capture the smaller particles as effectively.
Its a fact: Filtrete filters outperform all fiberglass, washable and non-electrostatic 1" residential air filters. These premium filters help remove allergens from the air, including smoke, smog, and even microscopic particles that can carry viruses, bacteria and odors.**
Microparticle Performance Rating (MPR)
3M developed the Microparticle Performance Rating (MPR) system to demonstrate a filters ability to capture the smallest airborne particles from 0.3 to 1 micron in size from the air passing through the filter. The MPR system helps you compare Filtrete filters based on the level of air filtration you want. The higher the MPR, the better the filters ability to capture particles from the air as it passes through the filter.
MPR is different from MERV, the Minimum Efficiency Reporting Value. The MERV system measures a filters ability to capture large particles. The MPR only takes into account the tiny microscopic particles between 0.3 and 1 microns.
* Electrostatic filters are most effective when clean and new.
** From the air passing through the filter.
